In Sharks and Rays of the World, Doug Perrine examines the bizarre evolutionary experiments that have characterized the development of sharks and rays, exploding the myth that they have been unchanged over hundreds of millions of years. He also explores their life history strategies, reproduction, feeding, body form, and sensory adaptations, all of which are highly advanced and unique among fishes, and he also reveals that rays, popularly perceived as a different set of creatures from the sharks, are so closely related that some scientists call them "pancake sharks." After providing a general description of the natural history of sharks and rays, Perrine then individually profiles some of the more colorful and popular species, including the great white shark, manta ray, whale shark, and electric ray. Lavishly illustrated with stunning color photography. For scuba divers and for readers from young adult+ interested in natural history and the sea. Hardcover, 10╜" x 9╜", 132 pgs, 80 color photos.
